1992 Honda Prelude, Ignition - Primary Waveform
Posted to the Waveform Library on 7/23/2002

The top wave form is the primary taken at the igniter while cranking. There was enough spark to fire a neon style spark tester but not enough to jump even a tiny gap. The bottom wave form is the signal from the engine computer.
